A corrosion-resistant epoxy powder coating is applied using an electrostatic process and oven-baked for a long-lasting finish. Complete hold down hardware kits are provided with all racks, and mount flange is pre-drilled for mounting ease using 3/16" diameter bolts. Use battery racks when mounting in a ventilated area. Specify make and model of battery and horizontal or vertical mount when ordering.
